To Reproduce Steps to reproduce the behavior:

The logic in edpm-ansible uses 'bootc switch' return code to tell whether it should create a reboot-required flag: https://github.com/openstack-k8s-operators/edpm-ansible/blob/ab5197732ee36aec11b5ac99a16d1640d3b27e17/roles/edpm_update_system/tasks/bootc.yml#L18-L40 

This is incorrect because 'bootc switch' will return 0 both on a successful switch, but also if there is nothing to do. Essentially the reboot flag will always get set regardless if we need to reboot or not.

Expected behavior

• Only set the reboot flag if reboot is needed (a bootc deployment is staged).

Bug impact

• Bootc deployments incorrectly signal that a reboot is needed when in fact it may not be needed.

Known workaround

• Instead of following the reboot-required flag, look at 'bootc status' and see if there is any deployment staged.
